drop down list in word 2003

I have a document that contains a drop down list in word when I email it in outlook 2003 the drop down list disappears. I am not able to send this as an attachment, it needs to be in the body of the email. I also can't send it as a picture because the document needs to be functional in the email. Any suggestions on how to get this list to stay or create a template in outlook with the drop down list.
